I used my friend's KX who was my roommate since he bought it new in 1976 for many years. I didn't find that the shutter was noisy, not any more than my own cameras, Nikon F2AS, Nikon F3HP, Nikon EM. A few years back I bought a used KX in excellent condition, still I don't think the shutter is loud but again like BMbikerider I must said there are many who would disagree with me.
Like BMbikerider, I would not class the KX as professional but it's Pentax top of the line (it was lower than the K2 but the K2 was automatic) like the Spotmatic before it and the MX after it.
The KX was the best K series camera with match needles metering (again I don't call the KM or K1000 match needle as they have only 1 needle) which show the shutter speed in used. It has the window that show the aperture. The photocell in the meter is silicon blue cell and is very accurate. It definitely a lot better than the famous K1000.
